Frame 5 Marine Discharge Module Installation
Follow these steps to install the frame 5 marine discharge module and conduit box.
1. Use the pilot holes in the conduit box bottom plate to drill the required holes for control and input/output power wire conduit fittings.
2. Turn off and lockout all input power, including any external power sources.
3. Wait 5 minutes and remove the box conduit cover, if present.
4. Measure the AC input and DC bus voltage to verify that there is not voltage present. See Frame 5 Drive Terminal Identification on page 4
for terminal locations:
• Measure the AC input terminals R/L1, S/L2, and T/L3, L to L, and L to chassis GND (PE).
• Measure the DC output terminals +DC and –DC, +DC to –DC, +DC to chassis GND (PE), and –DC to chassis GND (PE).
WARNING: Remove power before you remove cables or make cable connections. When you remove or insert a cable connector with power applied, an electric
arc can occur. An electric arc can cause personal injury or property damage in theses ways:
• An electric arc can send an erroneous signal to system field devices, which can cause unintended machine motion
• An electric arc can cause an explosion in a hazardous environment
Electric arcs cause excessive wear to contacts on both the module and its mating connector. Worn contacts can create electrical resistance.
